Sudowrite (sudowrite.com) is the most popular AI writing tool specifically built for fiction authors, novelists, and screenwriters. Founded by writers Amit Gupta and James Yu — with investors including the founders of Twitter, Medium, and WordPress — Sudowrite uses a proprietary model called Muse, trained specifically on narrative fiction rather than marketing copy or blog posts. Endorsed by bestselling author Hugh Howey, Sudowrite is designed to act as a creative co-pilot that helps authors draft, describe, expand, and revise manuscripts while preserving their unique voice.
How Sudowrite Works
You paste your manuscript into Sudowrite's editor. The platform reads your characters, tone, and plot arc to maintain context. The Write feature suggests the next 300 words in your voice. Describe generates sensory details — sight, sound, scent, texture — for any passage. Expand builds out rushed scenes with fuller prose. Rewrite offers alternative versions of any passage without replacing the original. Story Bible organizes characters, worldbuilding, synopsis, and plot into a structured document the AI references throughout your project.
